Is Glass Better Than Plastic For Water Storage?

May 8, 2026

Quick Answer

Glass is a better option than plastic for water storage due to its non-reactive properties and ability to maintain water quality, but it is more expensive and prone to breakage.

Why Glass is the Better Choice

Glass is a non-porous material that won’t leach chemicals into your drinking water, unlike some plastics. In fact, the US Environmental Protection Agency (EPA) has identified certain plastics, such as polyvinyl chloride (PVC), as having potential health risks due to the chemicals they release. Glass, on the other hand, is a safe and inert material that can store drinking water without compromising its quality.

Choosing the Right Glass Container

When selecting a glass container for water storage, consider the size, shape, and material of the container. Look for borosilicate glass, which is more resistant to thermal shock and less likely to break than regular glass. A container with a capacity of 1-2 liters is ideal for storing drinking water, as it allows for easy handling and storage. Make sure the container has a secure lid to prevent spills and contamination.

Additional Tips for Safe Water Storage

In addition to choosing the right glass container, it’s essential to follow proper storage and handling techniques to maintain the quality of your stored water. Always store water in a shaded or cool area to prevent bacterial growth and contamination. Regularly inspect your container for any signs of damage or contamination, and replace it if necessary. Finally, consider adding a water purification tablet or filter to your stored water to ensure it’s safe to drink in emergency situations.
